New high resolution transmission electron
microscope

As part of the membrane laboratory a high resolution transmission electron microscope (TEM) and a high resolution scanning electron microscope (SEM) has been installed. Beside the excellent optical properties both microscopes are equipped with actual analysis technique.

Thermal barrier coatings

Gas turbine blades are coated with ZrO2 thermal barrier coatings. Stresses lead to formation and growth of delamination cracks underneath the surface and finally to spaliation of the coating. Thermography visualizes the cracks with a detection limit of 0.7 mm width and 1 μm lift-off.

Thermo-mechanical Characterisation of Emission-Reduced Refractories

Novel, carbon-reduced and carbon-free refractory materials are developed within the DFG project “FIRE”. The work in Juelich is focussed on innovative testing methods for the thermo-mechanical characterisation. Investigations on the mechanism of crack growth and crack resistance as well as thermal shock experiments are carried out
